摘要
本文引出铁微量原素在人体内对带氧的生理作用,同时指出在青藏高原乏氧情况下,缺铁则更视为重要,乃对铁缺乏症与高原乏氧的相关,进行探讨。初步结果表明,除在体格方面年幼儿童发育较差、进入青春期呈现“后追”现象、肺活量示出与海拔高度成正比而进入青春期藏族大于汉族外,在血液方面重点突出改变为红细胞系。除与国际共识的随海拔升高而增高的有压积红细胞容积、红细胞计数和血红蛋白定量外,还显示出五项红细胞演算值即平均红细胞容积(1)、平均红细胞血红蛋白(2)、平均红细胞的血红蛋白浓度(3)、平均红细胞重量(4)、和平均红细胞原卟啉(5),显示各自特点:随海拔的升高而升高者有,(1)与压积红细胞一致;(2)和(3)亦然与血红蛋白一致但达4000米以上后,反而下降;(4)变化幅度与(2)(3)不同;(5)则独异,到海拔3000米以上则反而与海拔升高里相反趋势,即起下降,这些有待深入研究。
Abstract: It is well knrown that iron is an important element in formation of hemoglobin for carrying oxygen to tissue cells. Results of this study show: besides with delayed the physical development of children but catch up at school age and lung capacity increases as altitade getting higher, the hematological data shows peculier pattern. As altitude getting higher besides well known pattern internationally, MCV qetting bigger, but MCH and MCHC not so obvious increascng and as getting smaller as above 4000 meters above sea level; MCW and MCEP bolh qctting amaher as sea level above 3000 meters, just showing opposite tendecy.To be studied further suggested.
